what would you do differently ?

personally I may had done my own rear suspension geometry, but I can fully understand the apeal of using the ep3 setup
Should make it easy maintain in a rally environment with spares being handy. The frame and roll cage arangement to tie in the rossa chassis is spot on.

thought it would be that, if we cannot get the car passed for its log book as a rally car we have plans to potentially completely redo the cars geometry, make the front suspension inboard and such and then the same at the back, but currently we are keeping the suspension setup pretty similar to how it is.

Here are a few more photos, have got the brakes working a bit still a few adjustments to be made using mg tf cup brakes on the front and type r front calipers on the back but we're working on fitting rear calipers of some sort so that we can have hydro and cable handbrake.
We should be able to have a go up and down the driveway to make sure we're getting all gears and after that we just need to sort out all of the wiring, finish the wooden dash template and then make the carbon or fibreglass finished item, take most of the rear apart for final welding, fabricate the bulkhead back onto the car and any other fibreglass work that needs done, then paint it and check everything and that should be us good to go. so we still have a while to go yet :)

Not updated in ages, done quite a few bits here and there, one of the rear discs shown here as we work on the brake setup, not using type r calipers anymore but some rear mg tf's as regulations now require a cable handbrake, which is better anyway in case the car ever needs to sit on a hill
Image
Have been working on the huge air filters cradle, which is soon to be smoothed and painted
Image
Also done some work on the dashboard template, placing everything where we want it and making any minor adjustments before finishing the fibreglass work and making a mold of the whole item, then finish it off with a carbon fibre copy

Its been a while since I last updated we've been distracted with working on other projects that you can see if you head to our Facebook page, will try and get some photos of the progress of the wiring work that we've been doing. we managed to get our first little test which you can see here http://www.facebook.com/photo.php?v=691310267572693 just need to sort out a tiny leak thats giving us a lot of hassle and continue with the previously mentioned plans. Also first Airfield test hopefully coming soon :D

Looking good! What sort of brake pedal set up are you using? I noticed remote reservoirs along the scuttle. Are you using an all-in-one type pedal setup with the master cylinders mounted low down?

Nathan.

Hi Nathan we are using a KAD adjustable bias brake set up which has been cut and cranked to lower it to fit under bonnet. The clutch has been turned 90 degrees using a bell cranked lever which allows me to fit a different bore cylinder to suit the honda slave cylinder.

Just got the GTM back from Sitec Racing where they have had it on the rolling road mapping it so it idles properly and runs smoother with the custom intake and exhaust, car is making almost 200hp at the wheels which should be 230-240hp at the crank. combined with the cars weight which should be around 720kg when finished we'll have a bhp per ton of 330ish

We have cut and fitted new polycarbonate windows for the rear
Image
And for the sides which still need a bit of a clean up
Image
And we temporarily fitted the windscreen, windscreen wipers, motor and wired it all up

We went to a track night at Knockhill for the cars 1st proper test,
Image
Boy it is fast the acceleration is amazing, on the main straight we were quicker than 600-700hp M3s and the like but in the corners we were really struggling as the front brakes were overheating as we thought they might because we had put in bargain pads just for initial testing and the front ride height seemed to drop substantially more than we thought it would after settling in. As we became more used to the car and how it drives we were definitely becoming faster and faster as confidence grew but when on track we had to brake far too early so as not to boil the brakes, we we kept having to come in for a couple of minutes to let the brakes cool down and check for leaks, wheel torques etc.

When we got back to the garage we took the front wheels off and checked to see if there was anything else that we need to improve regarding the brakes, it appears the calipers are sticking a wee bit especially on the driver side so it looks like they will both need a rebuild as well as the right pads for the job. Looking at the front suspension the reason as to why the front ride height dropped so much is, it seems that the pin shown here at the top of the coil over even though already strengthened since this photo has bent on both sides we suspected this had happened when at the track but couldn't be certain.
Image
So we shall straighten the pins out and gusset them to make them indestructible or fabricate something similar and order the right pads for the job

sounds like good fun. Nice to have something different and show up some more expensive cars. Do you have any footage from the trackday?

A Go Pro is a among the TO BUY list so hopefully we'll have some soon :)
There was a photographer who seemed to be at all the right spots but we cant seem to find who it was
we did get sent these photos though

Since Knockhill in preparation for our 2nd test tomorrow at Kaimes we have shot blasted, repainted and rebuilt the front calipers with mintex rally/race pads. Fabricated new top and bottom shock mounts which will hopefully both be man enough for the job

Looking forward to seeing some footage when you get a Go Pro. Car is fantastic :P
